Making Just Intonation Play Along Tracks for Your Performing Ensemble (Using Tonal Energy and GarageBand)

There are a few things that would be helpful to know about my music teaching philosophy before reading this post.

1. I believe that tone production, intonation, balance and blend are central to teaching performing musicians. I prioritize them much higher than fingering technique, rhythmic precision, and even reading comprehension.

2. The way I structure my band classes starts with, is focused on, and always revisits those core ideas.

3. I have accumulated a vast variety of tools and teaching strategies to meet my goals of having superior tone quality, intonation, balance and blend. One of the most essential tools I use is the Tonal Energy Tuning app.

Tonal Energy Tuner

What is Tonal Energy? A hyper charged, power-user app for musicians that has many advanced features, including...

- Tuning drones that can be triggered polyphonically

- Feedback as to how in tune a performer is, which includes a delightful happy face to depict good or questionable intonation

- Drones and feedback can be adjusted to different temperaments

- A metronome (with more features than nearly any alternative on the App Store) that can be used separately or at the same time as the tuning drones

- Analysis tools that depict amplitude and intonation on an easy to read visual graph 

- Recording and play back practice tools for musicians to listen back to their performance

- Automated metronome pre-sets that can be sequenced 

See the video below. I will first depict the tuner playing a Bb drone, then I will show how it can model a Bb major triad all at once. Then I will turn the tuner to just intonation mode, and you will hear that the third and fifth of the chord are appropriately adjusted so that they are in tune with the Bb root. Next, the video will demonstrate how the metronome can be used in combination with these drones.

Imagine now that a student is playing a scale along with Tonal Energy. By leaving the tuner in just intonation, and centering around the key area of Bb major, every note of the scale that I touch will resonate accurately with the Bb, giving the student an accurate reference to blend into.

Developing An Inner Ear for Diatonic Intervals

Much of music is made up of scales. For a student to learn how to most accurately tune different intervals and chords, I have the drone running in the background during most of my teaching in whatever key area we are working in. I then move my finger to the correct notes of the melody to model and reinforce what good intonation would sound like. See below for an excerpt of a song my beginning students might play.

In the video below, watch as I play this song by dragging my finger along to the melody. This happens with a metronome to reinforce the beat. I like that TE has the option to speak counts out loud. In my experience, this really reinforces a concept of strong beats, weak beats, where in the measure the performer is. Other tuning apps have the counting feature as an option, but the sounds in TE sound more natural and less computerized.

Making Play Along Tracks in GarageBand

As you can imagine, I am doing a lot of dragging my finger along while students play for me. This gets tedious. I also want my students to be able to hear these pitch relationships when they practice, so I have begun recording them into play along tracks. How do I do this?

Inter-App Audio Apps and Audio Extensions in GarageBand

In the iOS GarageBand app, audio input is usually performed using either software instruments or by recording audio directly into the device with the microphone. But what you might not know is that you can also create a track that is based on the audio output of a third party audio app. If you have ever used a DAW, think of Inter-App Audio Apps and Audio Extensions like plugins. Once launched, you are kicked into a third party interface (much like using a reverb plugin from Waves or a synthesizer from Native Instruments) which then adds to or alters the sound of your overall project. In a more recent GarageBand update, Apple categorizes Inter-App Audio and Audio Extensions under the External option when you create a new track. 

Audio Extensions are effects that alter your tracks like reverbs and EQs, while Inter-App Audio captures the audio of a third party app and records it into its own track in GarageBand. You can browse the App-Store for Audio Extensions that work with GarageBand.

Recording an Inter-App Audio App Directly Into A GarageBand Project

Watch in the video below as I set up an Inter-App Audio App track with Tonal Energy. What I am going to do next is press record, and record my justly in tune play along of Lightly Row into my GarageBand project. I will do this using the euphonium sound. The euphonium drone is one of the roundest, darkest, and fullest sounds, while also containing a great range, so it is effective for most instruments to play along to while also modeling a rich, full, resonant sound.

Accurate Note Input with MIDI Controllers

In this video, you can really hear how sloppy the transition from one pitch to the next is when I drag my finger. Notice also that I did not play repeat notes. It is difficult to play the same pitch twice in a row without Tonal Energy changing itself to that key area. One way around these challenges this is to set up a portable MIDI keyboard with Tonal Energy. The one I have settled in is the CME X-Key with Bluetooth.

It has a sleek look, is very small, and has low key travel. It has buttons for pitch shifting and octave jumping. And Tonal Energy adapts to it in just intonation mode! Watch in the video below. As I change which chord I am playing, TE automatically snaps the third and fifth of each triad in tune, relative to the root. For my Lightly Row performance, I can now hold a Bb drone on in one hand, while playing a melody in the other.

Embellishing The Track with Other Instruments

The resulting play along track is alone pretty useful for students. Let’s make it more fun by adding a drum track.

We can make it even more fun by embellishing with bass and other instruments. I like to change up the style of these play alongs. Sometimes I don't even pre-record them, I just improvise along with my students to keep things fresh. Be careful though. These software instruments are NOT justly in tune, so too many of them can defeat the purpose. I try to combat this by having the drone be the loudest thing in the mix. Notice in this recording I have tried not to create any motion in the accompaniment that interferes with the consonant intervals in the melody, so that the listeners ears can remain focused on the drone for their reference.

Conclusion

Well, that's it! I can trigger these in rehearsal, sectional, and even share them with my students for home practice. Regular practice with tuning drones has really turned around my band's sound, and gives students the foundations for long term ear skills that will help them to HEAR what is in tune, not just respond to the commands “you're sharp!” and “you’re flat!”

Ethan Hein - Teaching Myself the Bach Chaconne with Ableton Live:

Gorgeous though the chaconne is, my enjoyment has been hampered by my inability to figure out the rhythm. All classical performers insist on doing extremely expressive (that is, loose) timekeeping. I don’t have the sarabande rhythm internalized well enough to be able to track it through everybody’s gooey rubato. Bach’s rhythms are complicated enough to begin with. He loves to start and end phrases in weird spots in the bar–the very first note of the piece is on beat two. So I needed some help finding the beat. A chaconne is supposed to be a dance, right? Bach wrote those note values the way he wrote them for a reason. Did he really want performers to assign any length they felt like assigning them? My gut tells me that he didn’t. I suspect that he probably played his own music in tempo, maybe with some phrasing and ornamentation but still with a clearly recognizable beat. I imagine him gritting his teeth at the rubato that modern performers use. Maybe that’s just me projecting my own preferences, but this sense comes from listening to a lot of Bach and performing some too.

So, I wanted to hear someone play the chaconne in tempo, just to hear how it works. And since no one seems to play it that way, I finally went and got the MIDI from Dave’s JS Bach MIDI page and put it into Ableton Live. I added a bunch of triple meter Afro-Cuban drum patterns to help me feel the beat, and had them enter and exit wherever I heard a natural section boundary in the music.

My personal favorite way to enjoy this piece is by performing it on vibraphone, but this is cool too. :)

The top audio challenge is to balance the music and the voice of our anonymous host to help the listener immerse in the story. I address it with a selection of iZotope tools. RX 6 is my go-to solution, and I also use Neutron, Alloy 2, and Ozone 7 to create the best sounding experience I can. The podcast is still being recorded in a spare bedroom somewhere in Australia, and there are a lot of challenges that come with that such as background noise, barking dogs, and neighbors. It's safe to say that without iZotope I would be lost!

Having invested in some of the Waves and Native Instruments audio plugins, I have never invested in iZotope. I only hear good things though.
